Ultrasound for primary confirmation of mechanical capture in emergency transcutaneous pacing

Clinical confirmation of mechanical capture in emergency transcutaneous pacing is sometimes difficult because of weak pulse volume or interference from skeletal muscle contractions. This report is of a case of using bedside ultrasound for primary confirmation of emergency transcutaneous pacemaker capture, and for differentiating between causes of persistent hypotension despite successful pacing. The technique of ultrasound-guided transcutaneous pacing is described.
